' SPECIFICATION forming part of Letters Patent No. 521,915, dated June 26, 1894.

' Application filed $eptember 25, 1893. Serial No. 486,599. (No model.)

To aZZ whom it may concern:

3e it known that I, CARTER H. PAGE, Jr., a c tlzen of the United States, residing at the clty of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and Improved Means for Lighting Gas Ranges, Heaters, &c., of which the following is a specification. I It 1s well-known that the burners of many types of gas ranges, heaters, and similar apparatus, are located in such positions as that access cannot be readily had for lighting them; consequently the employment of a jet burner for this purpose has been suggested. Hitherto the practical employment of such jet burners was attended withvseveral disadvantageous features Whichprecluded their use. For example, in order to project a burnlng gas jet, it is necessary to use pure gas, that is gas unmixed with air, and a jet burner supplied with such gas will, if left burning for any considerable length of time, cause a deposition of carbonaceous matter, which not only exudes a disagreeable odor but also collects in the fiues and passages of the range, heater, or other apparatus.

The principal objects of my present invention are, first; to obviate the above mentioned defects and disadvantages and to provide a gas range, heater, or the like, with a lighting jet that will not in use, permit of the deposition of carbon and its consequent disadvantages, and second; to provide simple, durable,and reliable means for lighting gas ranges, heaters, 850.

In my invention, useis made of a jet-burner provided with a spring controlled plug or valve tending to out OK the supply of gas and extinguish the jet and adapted to be maintained manually in position for permitting of the temporary projection of a lighted or burning jet into proximity with the burner of a gas range, heater, or similar apparatus.

The nature, characteristic features, and scope of my invention will be more fully understood from thei'ollowing description taken in connection with the accompanying drawings forming part hereof, and in which- Figure 1, is a perspective view partly in section illustrating a gas range having my improved lighting means applied thereto.

Fig. 2, is a central sectional view drawn to an enlarged scale and illustrating the jet burner shown in Fig. 1, and also its spring controlled plug or valve. Fig. 3,.is a side elevational view of the deviceillustrated in Fig. 2, showing the operating handle thereof turned into open and unstable position. Fig. 4, is an elevational view of the right-hand end of Fig. 3, and Fig. 5, is a transverse sectional view illustrating a jet burner embodying a modified form of spring controlled valve or plug.

I In the drawings, a, tea gas range provided with a burner 17, and with an oven 0, having between its walls and the casing a, of the range, passages d, for conveying the products of combustion from the burner 19, to the off take of the range.

e, is a jet burner in communication with the gas supply pipe Z), and disposed opposite an opening or aperture a in the casing a, of the range; so that a lighted jet may be projected from the jet burner 6, through the aperture a into proximity with the burner b, in order to light the same. However if the jet-burner 6, were permitted to continue to burn for any considerable length of time, carbonaceous matter would be deposited upon the bottom of the oven 0, and in the lines or passages d, and would thus not only prevent the free egress of the products of combustion from the burner 12, but also give rise to an unpleasant odor. To prevent these disadvantageous features, and insure the automatic turning off or exti'nguishment of the jet-burner e, as soon as the burner 12, has been lighted, use is made of a spring controlled valve or plug tending to close the jet-burner e, and temporarily restrained from such action during the operation of lightingthe burner 17, by the hand of the operator.

.Referring to Figs. 2, 3,and 4, the jet-burner 6, comprises a plug or valve f, revolubly mounted in the casing e, of the jet-burner and provided with a gas way f and with a discharge nozzle f This rotary valve or plug f, is provided with a rearwardly projecting spindle f, to which a sidewiseor'radially ranging operating handle f is secured by means of a set-screw f s, is a spiral spring connected at one of its extremities with the spindle f and at the other of its extremities with the casing e, and tending to turn the valve or plug f, into such position that the gas Way f thereof is out of alignment with the gas way e ,of the casing c, as shown in Fig. 2. hen the operating handle f is turned upward into the position illustrated in Fig. 4, the spring 5, is brought into tension or torsion and the gas ways f, and e*, are brought into alignment, thus permitting of a discharge of gas at the nozzle f As soon as the operating handle f is released, the resiliency of the spring 3, acting in conjunction with the weight of the handle f causes the valve or plug to be turned into such position that the gas ways f and 6 are out of alignment, whereby the discharge of gas from the nozzle f, is prevented.

The nozzle f is detachably secured into the valve or plug f, and is provided at its front end with a very small discharge opening. This construction is advantageous because it permits of the renewal of the nozzle f without necessitating the removal of the plug or valve f, and because such a small discharge aperture may be readily closed and redrilled to any required size.

The jet-burner illustrated in Fig. 5, is intended to be operated by a pull instead of a turn and in it, use is made of a needle-like plug or valve f adapted to co-operate with a nozzle (2 formed in the casing e", of the jet burner e, and provided with a rearwardly extending spindle f that penetrates the stutting box f and terminates in an operating draw knob f 8 is a spiral spring coiled around the spindlef, and having one of its ends in engagement with the collar 011 the spindle, and the other of its ends in engagement with the inner face of the stuiiing box. When the draw knob f is pulled, the spring is compressed and gas entering through the gas way (2 is permitted to pass around the needlelike valve or plug f and issue from the nozzle 6 However, as soon as the draw knob or haudle f is released, the spring .9 automatically forces the needle-like valve or plug to its seat and prevents a passage through the nozzle e. The mode of operation of the hereinabove described apparatus is as follows: To light the burner 11, the operating handle f Fig. 2, is turned, or in the case of the device illustrated in Fig. 5, the operating handle or draw knob f, is pulled, in either case gas issues from the jet-burner and may be readily lighted by means of a match, taper, or other lighting device. The valves 11 are then opened in order to permit a supply of gas to escape from the supply pipe I), and issue at the burner b. This lighted jet is projected through the aperture 0. into proximity with the burner l1, whereupon the gas or mixture of gas and air issuing therefrom is ignited. As soon as the burner b, has been lighted, the operator releases the operating handle of the jet-burner whereupon the spring of the latter immediately causes the burning jet to be extlnguished, as has been hereinabove explained, and this automatic extinguishment of the jet-burner is important because it prevents the deposition of carbonaceous matter in and around the lines and burners of the gas range.

Having thus described the nature and objects of my present invention, what I claim as new, and desire to secure by Letters Patent, is

The combination in a gas range, heater or similar device of a burner, a jet-burner, a spring tending to normally extinguish the jet-burner, and an operating handle for restraining said spring and permitting of the lighting and temporary combustion of thejetburner, substantially as described.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.
